Yep. I've seen it happen in brighter backgrounds too: but instead the fade will be a little darker (it does not happen on a white only wallpaper tho...) I was afraid it was an actual "feature", and this all kinda comfirms it. For now, a launcher will be the only "fix".

True! And to be honest, i kinda checked it again after your comment... (With no luck)

Haha no, it is not.

Really? I double checked on my other phone, there it was visible as well...

It does.

Hmm, i still notice some fade effect.. Edit: same on both devices.

That is what Fairphone said. But then, why do i have it and others don't? And why does this happen when i'm using a fully black wallpaper? It should be visible enough already...
